文摘

Pb(Zr_0.9Ti_0.1)O₃ pyroelectric thick films adding various amounts of the sintering aids Bi₂O₃-Li₂CO₃ have been deposited on the substrates Al₂O₃ by the screen-printing process, and the dependence of microstructure, dielectric and pyroelectric properties on the content of sintering aids has been studied. When the amount of Bi₂O₃-Li₂CO₃ increases from 0 wt % to 5.4 wt % , the sintering temperature of the thick films decreases from 1100 ¡ãC to 900 ¡ãC, and the grain size and the lattice constant decrease either, but the density and the dielectric constant increase. The Pb(Zr_0.9Ti_0.1)O₃ thick film with 5.4 wt % of Bi₂O₃-Li₂CO₃ sintered at 900 ¡ãC has the maximum pyroelectric coefficient 10.51¡Á10^?8 C/cm^?2 K^?1 and the highest figure-of-merit 10.58¡Á10^?5 Pa^?0.5.
